The carrier is disposed opposite to the fixed base and has a bobbin. The elastic element is connected to the fixed base and the carrier so as to provide freedom of movement of the carrier with respect to the fixed base. The imaging lens is disposed on the carrier and has an optical axis. The coil is disposed on the carrier. The magnetic element is disposed corresponding to the coil so as to provide a driving force for moving the carrier. The connection wire is disposed on the bobbin and electrically connected to the elastic element and the coil, and the connection wire has at least part facing towards the optical axis where the light-blocking coating is disposed.
